I don't like seeing people dedicated thier whole mindset to trading/gambling rather than the real Bitcoin investing. The mindset or mentality of trying to make a quick money/profit from Bitcoin is one of the biggest mistakes many people make, most of these people cannot even identify what thoer discretionary income is properly, and they get panic easily whenever the market becomes volatile. To me. Investing in Bitcoin should only happen when someone has confidence that then money they are using is actually a discretionary income and not the money needed for emergency bills or daily survival, so once that is clear, the next step is simply deciding how much you can be able to lose then how much ften to invest based on your personal finances strength. For example, if someone is earning higher income he may comfortably invest like 40% or 50% weekly while another person may or can only afford 10% or 15% monthly both are not bad. But what matters most just consistency with your discretionary income and invest for long-term growth, is far better to be buying $30 worth of bitcoin every week consistently than, purchase a $300 worth of bitcoin at once and later sell because you urgently need money emergency.
You make reasonable points. I was going to send you an smerit, except you misquoted me in your original version, so it looks like you posted my words.. which is misleading. You should fix your post quotes.
If you don't have discretionary income at the initial stage of your investment then what are you exactly investing with? As long as you don't need to to pay for your essentials it is your discretionary income and that's what you invest with, that's also what you use to set up your backup funds in which your emergency is one of them, you discretionary spendings where you treat yourself to certain pleasures that aren't exactly necessary or can be considered extravagant comes from your discretionary income.
People do a lot of things in their early stages of investing in Bitcoin and that includes investing when there is even no clear discretionary income. For instance, someone can decide to cut down on meals, from three square meals to eating once so that they can have extra income to invest in Bitcoin. People can cut down on expenses in many ways just to invest in Bitcoin. This may not be the best thing to do but beginners do it and then learn the best way of doing it with time.
My point is that a beginner can start investing in Bitcoin even when there is no clear discretionary income, but with time they will learn the importance of investing with discretionary income and even setting up emergency funds.
You cannot be "investing" in bitcoin if you don't have discretionary funds. If you are buying bitcoin with money that you need for your expenses, then you are gambling with money that you need for your expenses, so how could that be considered investing? With investing, you should expect to be using money that you can afford to lose, and also likely with a timeline that is 4-10 years or more into the future... but if you try to use non-discretionary funds then how is that going to work?
It probably is going to be better that you figure out some ways to increase your income and/or cut your expenses, which maybe is what you were trying to describe by buying ONLY 1 meal per day rather than 3 meals per day, and maybe that will work if you are still eating sufficiently enough to nourish yourself, yet it might be better to figure out ways to source your food with nutritious and inexpensive foods, since it could be problematic to overly skip meals.. even though you could cut down your portions and have small portions through the day, yet each of us still needs to assure that we are not contributing to our own health issues or loss of energy that could affect our abilities to earn income. I am not opposed to creative ways to cut some expenses, yet we still have to make sure that we are not overly cutting some of our expenses and/or otherwise undermining aspects of our health.
